Abstract
An electrical fixture is disclosed that has an electrical enclosure, a knockout plug coupled to the electrical enclosure with an interference fit, and a seal coupled to a circumference of the knockout plug between the knockout plug and electrical enclosure so that the seal provides an environmental barrier between an interior and exterior of the electrical enclosure. A method is also disclosed for providing an environmental barrier for a tapered-threaded knockout of an electrical enclosure including placing a seal on a knockout plug and pressing the knockout plug into the tapered-threaded knockout to establish an interference fit between the knockout plug and tapered-threaded knockout. The knockout plug is detachably coupled to the tapered-threaded knockout, with the seal providing an environmental barrier between interior and exterior portions of the electrical enclosure.
